* IMPROVEMENT IN BOLSTER-PLATES.

The Schedule referred to in these Letters Patent and making part of thesame.

To rwhomitanay concern." a a Beit "known that I, THOMAS .MORGAN, ofMarquette,ln the county of Marquette and State of Michigan, haveinvented a new and useful Improvement in Flanged Bolster-Plates; and Ido declare that the followingis a true and accurate description thereof,referencebeing had to the accompanying drawing and l to the lettersofreferencemarked thereon, and being a partof this specification, inwhiohl. t Figure Us a perspective of my invention, and

Figure 2is a longitudinal section of the same. t Like letters refertolike parts in each figure.

' The 'nature 'of this invention relates to the construction ofbolster-plates, with the necessary stakes combined,'and is designed tobe used as a cap or covering to the ordinary bolster. of awagon, therebyobviating the frequent breaking of the stakes as ordinarily used, andproviding a cover for the bolstei", by means of which it ispreservedfromthe action of the weather.

The invention consists in a cap,ca'st in any suitable metal, withflanges projecting downward, forthe purpose of covering the bolsteigtowhich it is secured by proper bolts; and is, also, provided with theuecessary stakes, the whole being cast in one piece. a V In the drawingfA represents my bolster-plate or cap, of cast-iron or other suitablemetal, provided with the downwardprojectiug flanges a.

Cast upon and to this bolster are the stakes B, with thestrengthening-flanges 71'. Y

e are bolt-holes, through which are inserted proper bolts, for securingthe plate to the'bolster. 1 I

A common wooden bolster is constructed, to the top of which is fittedthe cap, with itsflauges projecting down the sides of the bolster.

By the use of a device, as above described, the time. and trouble ofinortising the stake into the holster is saved; also, the liability ofthe stake breaking is greatly lessened.

After the wooden bolster has become worn, the cap can be removed, and anew bolster substituted for the old one; with but little expense.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is-

The flanged bolster-plate A, with downward flanges a, and provided withstakes, B, with sttengthening- 'flanges, b, cast vin one piece, inzconneotiou with and secured toa suitable bolster, when constructed asdescribed, and for the purposes set forth.
